In this study, the flotation behaviors of chalcopyrite and pyrite single and mixed minerals in Milli-Q water, NaCl solution, and sea water were investigated. The performance of different collectors was evaluated. Collectorless flotation was also studied under potentiostatic control to explore the...
In nature, the molybdenite ores are frequently associated with copper sulfide minerals such as chalcopyrite, and the flotation separation of copper-molybdenum (Cu-Mo) sulfides largely relies on the use of toxic and hazardous depressants such as cyanides, Na2S/NaHS. It is desired to replace these...
In the Sudbury Basin, froth flotation is commonly used to recover Pentlandite (Pn), and Chalcopyrite (Cp), while rejecting Pyrrhotite (Po), and other gangue minerals typically found in the region. However, as the sulfide minerals flow through the plant the surfaces continually oxidize, allowing...
